We all flinch at each uptick of gas prices, right? Well, factor in
this rule of
thumb: each 5 mph you drive over 60 mph is like paying an
additional 20 cents per gallon for gas.

The EPA is apparently quite confident that you wouldn't have any
inclination to go as fast as 65, and of course no one ever exceeds
the legal limit, so why waste time doing the numbers for 70, 75, or 80
mph?

If the sweet spot for fuel efficiency is in the 50's, as the chart
indicate, then as you get into the high 60's and above, the addition of
each mph requires more fuel than the last. This is explained in
greater detail at howstuffworks' article answering the question,
"What
speed should I drive to get maximum fuel efficiency?"
